I think I found what I need...it's a floating shut off solenoid inside a short pipe. If the level inside the sump return area gets too low the pump will shut down.
When the level goes up again the return pump will turn back on. Then I think I should use a siphon break at the return line into the display tank.
Am I on the right track? I'm just trying to avoid burning the pump up if for some reason the input side of the sump isn't getting any input. [smiley=confused1.gif] I was planning on using a weir out of the display tank.
